The response text may be lost when a recipient who has a MAPI account receives a meeting request response in Outlook

This article has been archived. It is offered "as is" and will no longer be updated.
In a Microsoft Exchange Server 2003 environment, a user who has a POP3 or IMAP4 account accepts a meeting request by using Microsoft Office Outlook, and then the user edits the response. However, the response text is lost when a recipient who is using a MAPI account receives the meeting response in Outlook.
The response part of a meeting request is composed into the DESCRIPTION property of the Internet Calendar (iCalendar) object if a user uses Outlook with a POP3 or IMAP4 account. When Exchange Server 2003 converts this iCalendar Reply object from the MIME mail format to the MAPI mail format, the DESCRIPTION property is lost.

Hotfix information

Note After you install this hotfix, a POP3 or IMAP4 client that responds to a meeting request puts the updates in the DESCRIPTION property, and this property is available in Outlook. Also, if there is an update in the COMMENT property at the same time, the data in the COMMENT property is maintained.

A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.
